PASANIA. 



main nerves 8 or 9 pairs, impressed on the upper, prominent on the lower, surface; 

 length of blade 4-5 in. to 7 in., breadth 2 in. to 25 in. ; petiole '25 in., stout. Spikes 

 erect, androgynous, in lax terminal panicles, slightly longer than the leaves. Female 

 .wen pretty numerous near the base of the spikes. Male perianth 5-cleft; stamens 10. 

 Female flowers solitary. Cupule sessile, campanulate when young, densely but minutely 



apiculate,

tomentose, minutely tuberculate, embracing half the glans. Glans ovoid, much 



glabrous, except the bases of the styles which are tomentose. Ripe cupule 



Borneo, Be Vriese. Beccari (without number). 



When he described this species, Miquel had seen only the leaves and young spikes 

 wbich are deposited in the Herbarium at Utrecht. Sig. Beccari's specimens have young 

 fruit, and it is one of these which I have figured. The species evidently belongs to the 

 Pasania group, in which its nearest allies appear to be pruinosa, Bl., and hystrix, Kortb.

Young parts densely covered with minute furfuraceous, fulvous, stellate tomentum. 

 Leaves coriaceous, ovate-oblong or elliptic-oblong, acute or shortly cuspidate, entire ; the 

 base acute; upper surface, even when adult, furfuraceous-pubescent ; the midrib and 

 nerves minutely tomentose; under surface pale, more or less densely furfuraceous- 



puberulous, except the midrib and 12 to 14 pairs of bold nerves which are fulvous 

 (often stellately) tomentose; secondary nerves transverse, distinct; length of blade 3*5 to 

 5 in., breadth 1*65 to 2*25 in. ; petiole *25 in. Flower spikes shorter than the leaves ; 

 those bearing females solitary and axillary ; the males in small, contracted, terminal 

 panicles; both densely tomentose when young. Hale flowers solitary or in fascicles, with 

 lanceolate bracteoles ; the perianth 6-cleft. Spikes of ripe fruit longer than the leaves, 

 axillary; fruit solitary, rarely with 1 or 2 abortive at the base. Cupule sub-sessile, 

 infundibuliform when young, finally becoming saucer-shaped ; the scales ovate, with long 

 spiny points, tomentose; in the younger states united only by their bases, leaving the 

 lono" verticellate, spine-like, curved, apices free. Mature cupule on a thick short stalk, 

 saucer-shaped, flat, embracing only the base of the glans ; *75 in. in diameter and only 

 •1 in. deep; the bases of the scales broad and entirely connate; the apices free, spread- 

 ing, or reflexed. Glans hemispheric, conic, crowned by the remains of the united 

 styles ; the base truncate, glabrous when ripe ; length, including the remains of the styles,

This is a considerable tree, attaining a height of 40 to 80 feet. It is allied to 



Sundaica, Bl., and to Q. pruinosa, Bl. From the former it is distinguished by its 

 greater amount of furfuraceous pubescence and more oblong leaves which are narrower 

 at the base, and by its more contracted inflorescence, smaller fruit with more echiuate
